TUCK-FOLDER.

SPECIFICATION forming part of Letters Patent No. 781,831, dated February'7, 1905.

Application filed November 21, 1902. ScrialNo.132,275.

To all wit/112i. it may concern:

Be it known that I. ALEXANDER Lannsonnu,

a citizen of the United States. residing at Bridgeport, in the county ofFail-field and State of Connecticut, have invented a certain new anduseful Improvement in Tuck-Folders, of which the following is a full,clear, and exact description.

My invention relates to improvements in tuck-folders forsewing-machines, and is designed and adapted more particularly for usein connection with family sewing-machines.

The object of the invention is to provide simple and effective means forpermitting the ready introduction and removal of the fabric forsuccessive seams, the guiding of the fabric with but slight attentionfrom the operator. and the ready adjustment for different widths oftucks and spaces or equidistant clusters of the same.

The invention consists of a tuck-folder having a folder-blade mountedupon a turntable which is provided with a fastening device per mittingthe adjustment of the folder-blade 5 longitudinally and laterally as thework de- T mands, as 1 will proceed now more particularly to set forthand finally claim.

In the accompanying drawings, illustrating the invention, in the severalfigures of which 3 like parts are similarly designated, Figure 1 is aside elevation. Fig. 2 is a top plan view. Fig. 3 is a top plan viewwith the folder-blade adjusted laterally. Fig. A: is a longitudinalsection, on a larger scale, taken substantially in the plane of the lineA B, Fig. 2. Fig. 5 is a cross-section on the scale of Fig. 4, takensubstantially in the plane of line C D, Fig. 2. Fig. 6 is a perspectiveview of the turn-table. Fig. T is a perspective view of the friction- 4washer for the turn-table.

The supporting-frame comprises a baseplate 1, having an over-reachingarm 2. provided with a returned end 3. Upon this returned end is mountedthe folder-blade A of ordinary construction, excepting as hereinafterspecified. This folder-blade has the index or setting scale 5, withwhich cooperates an index-finger 6, fixed in the end 3, whereby saidblade may be accurately adjusted for any desired width of tuck. There isprovided a 5 longitudinal slot 7 in the folder-blade to admit of thisadjustment.

The end 3 is provided with a vertical bore 8, counterbored at 9 toreceive, respectively, the hub 10 and flange 11, constituting parts 0fthe turn-table, as seen in Figs. 4: and The face of the flange 11 isprovided with a vertical rib 12, having parallel edges and of a widthaccurately to enter and engage the slot 7 of the folder-blade. Ascrew-threaded post 13, risingfrom the turn-table, carries a nut H,between which and the folder-blade is interposed a washer l5, restingupon the folderbladeand serving to transmit to it the pressure of thenut when said nut is turned down upon said washer to hold thefolder-blade upon the turn-table. The opposite side of the bore 8 isalso counterbored at 16 to receive a springwasher 17 or spring, and thehub 10 of the turn-table is screw-tapped to receive a shoul- 7o deredscrew 18, whose head bears upon the washer 17 in such manner as to puttension upon the turn-table with relation to the folderblade, and thushold said blade frictionally in place.

It will be seen that by the engagement of the rib 12 with the slot inthe folder-blade not only is such blade guided in its longitudinaladjustment, but that it is capable of lateral adjustment as well, asindicated in Fig. 3, without affecting the lixity of its longitudinaladjustment, and, further, that in both adjustments the nut 1% controls.

The spacing-blade 19 may be of usual construction, provided with a scale20 and coop- 5 erating with an index-linger 21, both the spacing-bladeand index-finger 21 being arranged upon the base-plate 1. Thespacingblade is provided with a longitudinal slot 22, through whichpasses the shouldered screw 23, having an interposed washer 2%, the saidscrew being tapped in the base-plate.

The frame is adapted to be removably secured to the bed-plate of asewing-machine, as by a screw passed through the hole 25 in thebase-plate.

The spacing-blade cooperates with the folder-blade in the usual manner.

Other variations in the invention are permissible within the principlethereof, since the gist of the invention is the provision of afolder-blade with a fastening device which serves not only as such, butalso serves to efi'ect a twofold adjustment of the folder-blade withoutinterference.

What I claim is 1. A tuck-folder for sewing-machines, having asupporting-frame, comprising a baseplate, an overreaching arm risingfrom said base-plate and provided with a returned end, and aspacing-blade applied to the base-plate, combined with a folder-bladeslotted longitudinally, a turn-table mounted in the returned end of saidoverreaching arm and provided with a vertical rib engaging the slot inthe folder-blade whereby said folder-blade maybe adjustedlongitudinally, a clamping device carried by the turn-table and actingupon the folder-blade to fix the longitudinal adjustment of saidfolder-blade upon said turn-table, and an independent frictionconnection between the turn-table and the returned end of theoverreaching arm, whereby the turn-table may be rotated axially so as toadjust the folder-blade laterally without disturbing its longitudinaladjustment.

2. A tuck-folder for sewing-machines, having a supporting-frame,comprising a baseplate, an overreaching arm rising from said base-plateand provided with a returned end, and a spacing-blade applied to thebase-plate, combined with a folder-blade slotted longitudinally, aturn-table mounted in the returned end of said overreaching arm andprovided with a vertical rib engaging the slot in the folder-bladewhereby said folder-blade may be adjusted longitudinally, ascrewthreaded post rising From said turn-table and provided with aclamping-nut and washer for fixing the longitudinal adjustment of thefolder-blade, and an independent friction connection between theturn-table and the returned end of the overreaching arm, whereby theturn-table may be rotated axially so as to adjust the folderbladelaterally without disturbing its longitudinal adjustment on theturn-table.

3. A tuck-"folder for sewing-machines, having a supporting-frame,comprising a baseplate, an voverreaching arm rising from said base-plateand provided with a returned end, and a spacing-blade applied to thebase-plate, combined with a folder-blade slotted longitudinally, aturn-table mounted in the returned end of said overreaching arm andprovided with a vertical rib engaging the slot in the folder-bladewhereby said folder-blade may be adjusted longitudinally, and aclarnpingdevice for fixing the longitudinal adjustment of the folder-blade, saidturn-table having a hub fitted in a bore in the returned end of theoverreaching arm, and a frictionwasher held between said end andturn-table to frictionally hold the turn-table in given position andpermit of its axial rotation to effect a lateral adjustment of thefolderblade.

In testimony whereof I have hereunto set my hand this 20th day ofNovember, A. D. 1902.
